Molecular Evolution of Anthocyanin Biosynthesis in Morning Glories
… processes following a gene duplication in the anthocyanin pathway. My results show that, prior to duplication, the DFR gene was constrained from functional improvement by its multiple enzymatic roles. Following duplication, this constraint was released and adaptive evolution proceeded along …

The modification of Anthocyanin biosynthesis in dicotyledonous plants
… aim of this study was to modify the pattern of anthocyanin biosynthesis in dicotyledonous plants, in particular legumes, using four different anthocyanin regulatory genes and two promoters. The anthocyanin regulatory genes consisted of a matched pair from maize and a mismatched pair from two …

Functional analysis of MYB112 transcription factor in the model plant Arabidopsis thaliana
… metabolism. We report enhanced and impaired anthocyanin accumulation in MYB112 overexpressors and MYB112-deficient mutants, respectively. Expression profiling reveals that MYB112 acts as a positive regulator of the transcription factor PAP1 leading to increased anthocyanin biosynthesis, and …

Regulation of anthocyanin accumulation in apple by the transcription factor MdMYB10
Anthocyanin concentration is an important determinant of the colour of many fruits. In apple (Malus x domestica), centuries of breeding have produced numerous varieties in which levels of anthocyanin pigment vary widely and change differently in response to environmental and developmental stimuli. …

Analyse und Visualisierung eines R2R3-MYB / bHLH Transkriptionsfaktorkomplexes aus Arabidopsis thaliana
… characterized already. A regulated procedure of biosynthesis without frictionless and functional cooperation of many regulatory transcription factors is not possible. In this work, three different transcription factors were analysed in detail, MYB75 as well as BHLH2/BHLH42 and TTG1. These are …

Understanding the development, evolution, and function of bullseye pigmentation patterns in Hibiscus trionum
… with a striated cuticle, and are pigmented with anthocyanins. A minimal regulatory network restricting anthocyanin pigment production to the bottom of Hibiscus trionum petal was identified. The network relies on two MYB regulators: HtCREAM1 which represses anthocyanin production in the top of the …

Identifying and characterizing genes and transcription factors involved in coloration of apple fruit
… Red coloration in apple fruit is attributed to anthocyanin accumulation. Anthocyanins are encoded by structural genes, in the anthocyanin biosynthetic pathway, which are highly regulated by transcription factors. In this thesis, studies were conducted to identify and characterize structural …

Flavonoid diversification in Hibiscus and its impact on petal pattern evolution
… are formed by flavonoid pigments including anthocyanins and flavonols. Their flowers display a contrast between a purple base and an off-white distal region. H. trionum belongs to the Trionum Complex native to Australia and New Zealand, whose members vary in bullseye size and colour. This …

The transcriptional regulation and health benefits of anthocyanin in Actinidia (kiwifruit) species
Anthocyanins are plant secondary metabolites that colour flowers and fruit red, purple, and blue. They belong to the flavonoid class. The accumulation of anthocyanin confers protection against photooxidative effects and attracts pollinators and seed dispersers. Anthocyanins in fruit act as an …

Estudio del origen genético de la variedad de vid Garnacha Blanca, de su diversidad fenotípica y de los efectos moleculares asociados a la variación en el color de la uva
… and indirect consequences of the absence of anthocyanins in berry composition using metabolomic and transcriptomic analyses. Results showed us that the main variable determining variation in production and bunch compactness is fruitset rate and it has strong environmental dependece. Traits …

Genetic studies of phenotypic variants in the woodland strawberry, (Fragaria vesca)
… include alterations to floral development, anthocyanin pigmentation and leaf structure. The floral development mutant named green petal (gp) was not associated with the T-DNA insertions present. Based on similar phenotypes induced by mutation of transcription factors involved in floral …

Genomic and genetic resource for soybean disease resistance improvement
… respectively. CHS6 is involved in stress-induced anthocyanin biosynthesis, which could be involved in seed-coat mottling. Additionally, two loci associated with seed number index were identified in the second population. One of these two loci confirmed one quantitative trait locus (QTL) associated …

Molecular Genetic Analysis of Cyclic GMP Signaling in Higher Plants
… demonstrated that sucrose is a potent inducer of anthocyanin biosynthetic gene expression and that its inductive effects are mediated by the small signaling molecule cyclic GMP (cGMP). In addition, sucrose is an inhibitor of phytochrome-regulated gene expression, but the manner in which it …
